Instructions

Combine butter and brown sugar. Beat with a mixer until smooth. Add eggs and beat well. Add extracts, buttermilk and orange rind. (Mixture will seem to separate.) Add flour 1/2 cup at a time, beating just until combined. Gently fold in blueberries.

Spoon batter into muffin liners (a heaping 1/4 cup per muffin). Place in oven and bake 30 minutes, or until light golden and springy to the touch. Sprinkle turbinado sugar on tops. Cool in pans 15 minutes. Remove and serve warm.
